Hei Husbando

Hei (黒（ヘイ） , pinyin: Hēi, lit. Black), also known as the Black Reaper (黒の死神 Kuro no Shinigami) or BK-201, is a human who gained Contractor powers. He has worked with various organizations including the Syndicate and CIA. He is the older brother of Bai. As a member of the Syndicate, Hei regularly takes on false identities and personas for his missions and day to day life, such as Li Shengshun (李生舜 (リ・シェンシュン), Ri Shengshun, pinyin: Lǐ Shēngshùn): a good-natured, timid Chinese exchange student who tries to help others but otherwise generally keeps to himself. Hei is a calculating assassin. Unusually for a Contractor, Hei exhibits and sometimes acts upon emotions. Hei also has a huge appetite, often surprising people with the amount he can eat. Despite having the power of a Contractor, Hei still has his human emotions. He deeply cares for his sister, Bai, and searches for her after her disappearance. source: https://darkerthanblack.fandom.com/wiki/Hei
